摘　　要：ＣＯ２加氢直接制取二甲醚的研究葛庆杰黄友梅１）邱凤炎李树本（中国科学院兰州化学物理研究所兰州７３００００）关键词二氧化碳催化加氢二甲醚铜催化剂分类号Ｏ６４３．３２二氧化碳在地球上含量极丰富，且随着工业的发展而日益增长．同时二氧化碳含量的日益增多，会加...The effects of catalyst reduction temperature and reaction conditions on the reaction of CO 2 hydrogenation to dimethyl ether were investigated. The following results were obtained:① Catalyst reduction temperature has no evident effect on the reaction, the suitable reduction temperature ranges from 240℃-270℃; ② With increasing reaction temperature, CO 2 conversion and CO selectivity increase, but DME selectivity decreases. Above 240℃, CO 2 conversion decreases with increasing reaction temperature. ③ Increasing pressure and decreasing GHSV are benificial to the reaction of CO 2 hydrogenation to DME, with increases of CO 2 conversion and DME selectivity and decrease of selectivity to byproduct CO.
